MapLooper is a live-looping system for gesture-to-sound mappings.

We developed a connectivity infrastructure for wireless embedded musical instruments with distributed mapping and synchronization. We evaluated our infrastructure in the context of the real-time constraints of music performance. We measured a round-trip latency of 4.81 ms when mapping signals at 100 Hz with embedded libmapper and an average inter-onset delay of 3.03 ms for synchronizing with Ableton Link. On top of this infrastructure, we developed MapLooper: a live-looping tool with 2 example musical applications: a harp synthesizer with SuperCollider and embedded source-filter synthesis with FAUST on ESP32. Our system is based on a novel approach to mapping, extrapolating from using FIR and IIR filters on gestural data to using delay-lines as part of the mapping of DMIs. Our system features rhythmic time quantization and a flexible loop manipulation system for creative musical exploration.


We open-source all of our components:
